-Application filed October 14, 1910. Serial No. 587,083. To it may concern:

Be 1t known that I. James I. CRAVEN, a resident of Pittsburgh. in the county of Allegheny and State of Fe ay also have screwed thereon a delivery spoutif desired.

The substance is forced from the rece nnsylvania, have tacle through the del projection m l ivery orifice by means invented a new and useful Improvement in of a piston or follower 9 which is longi- Receptacles for Containing and Discharging tudinally movable therein, such as by hav- Pasty Substances, of which the following is a specification.

-This invention relates to a receptacle for containing, storing, transporting and dis charging semi-solid and pasty substances.

The device is intended more particularly for putting up lubricants in the form of grease and discharging the same into the l grease cups of machines so as to enable the grease to be su )plied to the bearings without liability oi dirt or grit entering the Semisolidand mg its periphery threaded V and engaging the threads on the/interior of the tube or receptacle 1. so that when said pistolcis rotated it moves longitudinally in said tube. For the purpose of rotating the piston there.

id will bjeso mounted as to be longitudinally immovable, bl trotatable so that when turned it turns the piston and thereby causes bearings with the grease and also to prevent the latter to travel longitudinally in the smearing u or soiling the machinery or tube. arious means for holding and turnthe hands of the user. The invention, however, is not limited to this particular use, but is adapted for put-ting up in a substantially sealed condition any semisolid or pasty substances and delivering the same from the container in any desired quantity or quantities.

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawing Figure 1 is a vertical section through the improved device; and Fig. 2 is a horizonta section on the line 2-2, Fig. 1.

The receptacle or container may be made of any desired size or shape and may be constructed or built up in any desired way or from any desired material. As shown in the drawings the receptacle is formed by a substantially cylindrical tube 1 which prefing the r d 10 may be'employed. s shown,

rotatably mou movable on the tube 1, such as havln edge crimped around a flange or shoulder on the body. Preferably the annular ed of said cap is knurled or milled, as at I to give a good grip for the fingers t0 r0 late the same. It. is obvious that when the cap 12 is rotated the piston 9 is also caused to turn, and on account of its threaded engagcment in the interior of the tube travels longitudinally in the latter thereby forcing the grease or other substance out through the discharge orifice.

The receptacle is filled either through the dischar 'e orifice 5 or by removing the cap 3. It IS filled with the substance at the its 13 erably is formed of sheet or other suitable factory and is then closed by means of cap metal, or other substance capable of having, 6 so that it is practically sealed. In this condition it ca formed into or provided on the instored without th the threads 2. One end of this receptacle is-closed by means of the cap or head 3, which preferably is removable such as by having a threaded connection with the body at 4, for convenience in filling the receptacle with the desired material. This head'is provided with the discharge orifice 5 which preferably is formed in an extension by one hand and the cap 12 or cap, which extension is turned with the other hand. hereby causing externally threaded to receive the screw cap the piston to travel longitudinally and forcforming a closure, and which threaded ing the substance out of the receptacle.

its walls terior W1 i and having a This operation can be readily performed so that it is )ossible to accurately gage the quantity of n'iaterial forced out of the receptacle and also preventing the soiling of the users hands.

Various other means than the p ay be provided for rotating the operating rod 10, as will be readily apparent,

\Vhat I claim is:

1. A device of the character described comprising a thin light tube spirally corrugated to provide internal. threads, a cap closing one end of said tube and provided with a discharge orifice, a piston or follower threaded on its periphery and engaging the internal threads in said tube, means longitudinally immovably mounted in said tube sliding fit with said follower, and an im erforate end closure at the opposite end 0- the said tube arranged for rotating said means to cause the piston to discharge the contents from the discharge orifice.

2. A device of the character described comprising a thin light tube spirally corrugated to provide internal threads, a cap closing one end of said tube and provided with a discharge orifice, a piston or follower threaded on its periphery and engaging the internal threads in said tube, an imperiot rate cap closing the opposite end of the tube i and being rotatable but longitudinally immovably mounted thereon, and a rod segcured to said cap and extending into the i driving connection with said rod.

In testimony whereof, I have hereunto set my h nd,
